Are you sure it's meant to come off? I had a faucet that I tried to take a
part and it turned out to be just an el cheapo that you could not
disassemble.

Maybe try going to Delta's web site to see of they have an exploded view
diagram of your faucet, or just search the web with your faucet part or
model number to get the diagram, then you can see what parts are meant to
come off.

It looks like it's supposed to come off. At least the cap is a distinct
part.
